DoUoHn MEANS.

Application filed September26, 1924. Serial No; 740,077.

This invention relates to means or douches for irrigating and cleasingwounds and diseased tracts or canals in bodies such as the uterus, thevaginal or genital passage, and '5 the alimental canal, for the treatment of endometrial, cervical and vaginal diseases,; to remove offensive discharges, secretions and deposits, and to supplement the healthy activity of the tissues, and it is the'primary object of the i'nv-ention to provide an im- A further object of the invention relates to apparatus for this purpose embodying therein a receptacle or chamber for receiv ing the discharged irrigating liquid or lotion after it has been applied to and drawn off from the diseased part with any unhealthysecretions for the purpose of mak ing a diagnosis of the same.

Another object of the 1nvention relates to an improved constructed and arranged injectingand ejecting nozzle and the provision of means to prevent the escape of liquid ao-when applied to a cavity in the body-*with the resultant wetting of the clothes of the one being treated or the one administering the treatment. i A still furtherobject of the-invention relates to an improved suction creating means for drawing olf the irrigating liquid after it has been applied to, the diseased part.

Other objects and advantages 'will hereinafter'appear.

In the drawing accompanying and forming a part of this specification Figure 1 is an elevational view of an installation of my improved douche apparatus to show the manner of utilizing the same as a douche and as an irrigating means to draw off the medicated liquid or lotionafter it has been in of the drained'ofi liquid for the purpose Figure 3 is a side elevation, partly in section, and on an enlarged scale, of my im v proved suction creating means; and,

'Fig'ure 4, is a side e1evation,*partly in'sec tion, showing my improved nozzle connected directlyto a liquid carryingreceptacle. Similar characters of reference designate flike partsthroughout the dillerentviews' of the drawing. i

I lInfcarrying out the invention thereis provided acombined injecting and ejecting nozzle, fcomprising a pair of concentric chambers, the inner chamber consisting of a' tube 5 having one end constituting the inlet end, enlarged as at 6, and the-opposite end arranged with the usual fluted nozzle 7 having discharge outletrmeans inthe form of an orifice or'orifices 8, The inlet end has a coupling 9 releasably connected thereto, as by screw threads 10, for the connection of a hose or tubing 11 to connect the inner chamber or tube 5'with a source of supply or medicated liquid or lotion, in the present instance, shown as an irrigating bag 12, which in use is suspended at some elevation wherebythe'irrigating liquid flows through the inner chamber by gravity. The tube 5 is 'made of suitable material preferably vulcanite;

The other-chamber is in the formof a casing or tube 12 preferably of glass where'- the same may be readily cleansed. This tube is of a'diameter greater than the tube 5 to provlde a space or an outer-chamber 13 between the tw0tubes,"the tubeg12 preferably being of a diameter to'lie contiguous to the enlarged inlet end Gandflutes of the nozzle 7 in the inner tube 5. The tube 12 extends from the inlet'end of tube 5 and adj acentto theend ofthenozzle 7, but preferably terminates at a point within thenozzle orifices, the spaces between the flutes of the nozzle and open end of the tube 12 A serving as inlet means to said outer chamber 13 for the'entrance of liquid ejected I from the nozzle orifices. applied to a diseased part and the collect- The opposite end of the tube 12 is closed by a perforated cap 14 or pliable andyield ing material, such asrubber, said .cap embraci'ngithe end of the tube 12 whereby said tube is mounted upon the-inner tube '5 at the inlet .endfthere'of by clamping said cap "between the end of tube 5 and a laterally extending' flange of the coupling-9, as at 15. The liquid ejected fro-inthe nozzle and subsequent to the irrigating of the diseased part enters into the chamber 13 and is dischared or drawn off from said latter chamher through an outlet in a projection 16 extending laterally from the tube 12 adjacent to its mountin upon the tube 5, said tube projection 16 being arranged for the connection of a hose or tubing 17 thereto as shown in Figure 1.

In the use of thedevice as a douche with the person bein treated in a reclining position, as in a be to irrigate the uterus and vaginal or the alimentary canal the discharged or drawn .011 ll uids may be led to and collected in a suit: yle receptacle, such as a an 18, by the tube 17 as shown in dotteiflines at 17". In such use of the irrigating apparatus to prevent escape of the irrigating liquid from the passage or canal being treated a shield is provided which is adaptedto snugly lit the wall of the outer chamber of the nozzle and readily adjust itself to the wall of the passage or canal. This shield comprises a member 19 of elastic material, such as rubber, substantiallyof trusto-conical shape with the wall diverging outwardly and rearwardly of the nozzle '7. It will be obviousthat the nozzle may be inserted into the vaginal or alimentary canal to a Variable extent and then the shield ad ju md along the nozzle inrcontiguous rela' tion to the wall of thecanal.

To assure the drawing oil' of the irrigating liquid from the chamber 13 suction means is provided. This suction creating means consists of a device adapted to be applied to a water .faucet and the how of water from the faucet causin the airto be evacu ated, or partially so, from the chamber of the casing 12 through the tube 17, and comprises a pair of ice-axial chambers 21, 22 (Figure 3), the chamber 21 cnstituting a pressure chamber and the chamber 22 an air chamber and having less area than the chamber 21. The air chamber 22 has an outlet in an axial tubular projection 23 to which a flexible hose or tubing 24 is adapted to be coupled, and the chamber has an inlet throu h a tubular projection 25 extending laterally fromethe casing of the chamber and three h which the tubing 17 is connected. The cliaiuber 21 is arranged in an inverted cone shaped casing open at one end and having a perforated closuae (for said opening. To adapt the same to be readily attached in water tight connection with a faucet 26 (Figure 1) this closure consists .of a metallic cap .27 having threaded connection with the casing of the chamber having an axial perti'mation with a disk 28 of flexible or yieldin material, such as rubber, clamped between t to perforated cap 27 and the chamber casing, as at 29, as the cap is threaded to the casing, said disk having an opening axially of the chamber of less cross sectional dimension than the opening in the cap for in dotted lines at 32, with" the outlet projection 31 extending adjacent to but spaced from the inlet to the projection 23 and; hes

ing restricted relative to the outlet in said latter projection. The stream of water entering the water chamber is of greater volume than the discharge of said liquid from the restricted outlet 31 with the result that the water in said chamber is placed under pressnre and forcibly discharged from the outlet of said chamber, said discharged stream as it passes through the gap or space be tween the outlet 31 and the inlet to the out lot 23 of chamber 22 induces a flow and exhaust of the air from the chamber 22, which creates a suction in the tube 17 and connected chamber 13. i

To collect the drawn-oil irrigating liquid for the purpose of diagnosing the same a receptacle 33, which may be a jar orbottle,'is interposed in air tight connection in thetube 17. For this purpose the receptacle openin is provided with a removable sto perfi t 0 rubber having a pair of elbow to c 35, 36, preferably of glass, in communication with the receptacle through perforations inthe stopper and having air tight connection therewith, a, section of the tubing 17 connected to the outlet 16 of the casin 12 being connected to one of said elbow to es, as the tube 36, and the other section of said tubing 17 connected to the inlet of the air chamber of the suction creating deviceoonnected to the tube 35. The suction creating device evacuates the air from the receptacle 33 and thereby from the chamber 13 drawing the liquid discharged from the tube 5 into and from the chamber 13. The tubes -35and .36 extend only to a slight extent into the receptacle 33 and out of contact with any liquid which may be collected in said receptacle, the

one tube extendinginto the receptacle to a slightly greater extent than the other, as shown, to prevent the drawing of the liquid from the one tube into the other.

In Figure 4 I have shown a unitary structure of nozzle and irri ating liquid su ply receptacle, this receptac e being in the orm of a bulb 12' having an outletin a projectin portion 37 to which the end of the nozz e tube 5 is connected by inserting the same therein. The tube 12 cocrating with the nozzle tube 5 to promde tie chamber 13 is enlarged at one end and on aged over the :bulb projection 27. The device may be also arranged with the shield 19.

While the invention has been described as particularly adapted for the treatment of disease of the genital canal or vagina and uterus it is also applicable for the treatment the receptacle to the nozzle, and a tubular 7 member mounted at one end upon the tubular portion ofthe receptacle in which the nozzle is engaged and serving to clamp the nozzle in the receptacle outlet, said tubular 'memb'er extending around the nozzle in spaced relation thereto to form a chamber between said member and nozzle with the outlet end of the nozzle extending slightly beyond the open end of the tubular member and the space between the open end of the tubular member and nozzle serving as an inlet to the chamber, and said tubular member having an outlet in, a nipple extending laterally adjacent the end of the tubular member at which it is mounted upon the tubular outlet portion of the receptacle for the exhaust of liquid from the chamber between the nozzle and tubular member, and a flexible conical shield engaged upon the tubular member for adjustment longitudinally thereon.
